@param index the index of the byte value to be returned

@return the specified byte value as character or the FNC1 character

@throws IndexOutOfBoundsException if the index argument is negative or not less than length() @throws IllegalArgumentException if the value at the index argument is an ECI (isECI)

Implementation
